TPS4100

FOUR CHANNEL BRIDGED OUTPUT POWER STAGE

Rev i sion 2.5 - February 2005

GENERAL DESCRIPTION

The TPS4100 is a 4 channel bridged (16 power transistors) output power stage. The TPS4100

accepts 5V CMOS logic signals from a Class-T processor, such as TCD6001, to create a high

fidelity 4 channel audio amplifier. The TPS4100 has been designed specifically for automotive head

unit applications operating on a single 10-26V supply.
